Hello i have strange mixin crash when i run client (sorry for using that crappy mod maker :D)

Adding "property 'mixin.env.disableRefMap', 'true'" fixed error with itemstack mixins

But now i'm getting other crash:

You need to specify the remapping file too.

property 'mixin.env.remapRefMap', 'true'
property 'mixin.env.refMapRemappingFile', "${projectDir}/build/createSrgToMcp/output.srg"
